People diagnosed with schizophrenia have an increased risk of developing Parkinson's disease later in life, researchers report. The reason could be due to alterations in the brain's dopamine system cause as a result of dopamine receptor antagonists or neurophysiological changes associated with schizophrenia itself. Read More
New studies are set to explore how gene expression alters the brain's response to drug abuse, and to screen for genes that could help brain cells withstand Parkinson's disease. Read More
